I. Sources of Imaging Spectrometry Data

Sources of imaging spectrometer data are varied. A brief summary of some historical and currently operating systems is presented as the following table.

Note that the number of spectral bands and the range of spectral coverage varies. Also be aware that there are no standards for geometric, or radiometric calibration of data from these systems. Many are experimental systems and were developed to address very specific questions.

There are Federal guidelines for geographic data that are applied when acquiring data for orthoquad production, for example. There are also draft standards for aerial photography, and working guidelines for the acquisition of digital imagery to help users acquire remote sensing data that will meet their needs.
